My present invention relates to surgical instruments and has moreparticular reference to an implement for use by surgeons,

hysicians, and others for the removal of eans, peas, and similar smallobjects from the nasal, auricular or other cavities.

As is well known, children while playing with small objects frequentlyinsert them into their nostrils, and the cavities of their ears, andwhen this is done with beans, peas, and similar objects, it is quitedifiicult to remove them with the ordinary facilities avail- Applicationfiled November able to the parents or other attendants of the children.This difliculty is due chiefly to the fact that the object isusuallyround or has I a smooth curved outer srface which it is almostimpossible to surround or engage in a proper manner to withdraw theobject. Numerous structures have been devised for the purpose ofperformin the function mentioned, but few of them ave met with anydegree of success.

It is therefore an object of my invention to provide an instrument forperforming such an operation that is simple in both construction andmode of operation, and which is also of a dependable character so thatit may be readily used by a careful person and therebyavoid injury tothe adjacent or surrounding tissues of the cavity in which the foregoingobject has become lodged'. My device is so constructed that it may bereadily separated for the purpose of sterilization; it is of smallproportions so that it will occupy but a restricted space in amedicineor instrument cabinet when not in use; and its parts are of sturdyconstruction so as to j'insure dependability when in use.

The foregoing features of my invention I prefer to accomplish insubstantially the manner hereinafter fully described and as moreparticularly pointed out in the appended claims, reference being nowmade to the accompanying drawings that form a part of thisspecification.

In the drawings:

Figure 1 is a perspective of my instru- 4 ment showing the partsseparated for the purpose of clearness;

Figure 2, is a bottom plan of the instrument with the parts assembled.

Figure 3 is a transverse section on line 3-3 of Figure 2.

enlarged scale the manner of insertin the instrument into a cavity, theforwar one of the object-engaging prongs being in the position of passinthe lodged object.

Figure 5 is anot er schematic view showing the manner of gripping theobject to withdraw it from the cavity.

In the drawnigs I have employed similar reference characters todesignate the same parts wherever the same occur throughout the severalviews.

Referring to Figure 1, which illustrates a typical or preferredembodiment of my invention, it will be seen the instrument comprises twomembers A and B the former of which consists of a rod or shank 10 thatis a straight wire or the like one end of which is tapered into a point12. The portion of the rod or shank immediately adjacent the point isprovided with a substantially half bend 13 so as to dispose the point 12rearwardly or towards the oppo site end of the shank. At itsother endthe wire forming the member A is given an abrupt lateral bend 14 and theportion beyo'nd this bend is curv (1 into a segmentall shape to providea finger grip 15.

The member B of the instrument is in the form-of a tube 11 of greaterlength than the straight rod or shank portion 10 of the member A and 'itis adapted to be telescoped over this shank portion whereby the fingergrip will project through a longitudinal slot 16 in the underside of thetube 11 so that it will slide therein when the members A and B are movedrelative to each other as! hereinafter described. .The rear portion ofthe tube is opened out flat and-is curved downwardly to provide aconvenient hand grasp 17 substantially in the same manner as the fingergrip 15 of the companion member A of the instrument. At the outer endthe tube is bifureated and the metal upon each side of the slit thatprovides this bifurcation is flattened and tapered topoints that providespaced prongs 18, 18. It is desirable though not essential to bendtheseprongs downwardly and spread the r ends -apart slightly as seen inthe drawings so that the points thereof will be disposed upon each sideof the axis of the tube and rod substantially in alinement with thepoint of the hook on the outer end of the memher A of the instrumentwhen in use. As

will be seen in the sectional view, the interior dimensions of the. tubeis sufiicient to slidabl receive the shank 10 of the member A, an fromthe bend 14 downwardly the wire is flattened or reduced in diameter sothat the finger grip will readily enter the slot 16 of the tube, thanthe diameter of the wireof which the shank is formed, guiding themembers A and B during relative movement and pre? venting thedislodgement of the shank while performing an operation.

When it is desired to use the instrument the members A and B may beseparated by withdrawing the former from the outer end of the latter.The hookedend or the member A is inserted in the cavity between thetissue and the foreign object with the hook positioned fiatwise withrelation to the object so that the tissue is not unnecessarily distendedor irritated, and as soon as the hook has been moved past the object theshank is rotated about a quarter of a turn so that the pointed end 120ithe hook will be in to position to engage the inner surface of theobject. The member B of the instrument is then slid on to shank 10 withthe prongs 18 towards the object and with the finger grip 15 projectingthrough the slot 16 of the tube. Continued movement of the tube upon theshank brings the prongs into the cavity and into engagement with theouter surface of the object and opposite the point of the hook. lheoperator now grasps the finger gri 15 and handle 17 and upon exertin asight pressure towards each other will able to firmlygrip the objectbetween the' point of the hook and the prongs, and upon withdrawing thewhole structure simultaneousl will remove the object from the cavity. emode of operation may be varied by telescoping or assembling the membersA and B, allowing the hook of the shank to protrude say an inch beyondthe prongs. The hook may be inserted in the Y cavity and positioned asbefore described,

afterwhich the tube is slid up and the prongs engaged with the object sothat it is firml glip ed for removal. k

, It wil o vious to others that changes or modifications in the precisestructure herein disclosed may be made without departing from: theprinciples involved, and I therefore desire it ex ressly understood thatall such changes, mo ifications or alterations. are fully contemplatedas coming within the scope of the appended claims.

which slot is of lesswidth What I claim 1. A sur ical instrumentcomprising a rod, a pointed ook at one end thereof formed by giving therod a reverse bend so that the point projects rearwardly, a lateralfingergrip at the rear end of the said rod, a tube telescopic on saidrod and provided with'a longitudinal slot extending from end to endthrough. which the finger grip projects to maintain the relativeposition of the hook and permit the ready removal of the rodlongitudinally from the tube, ly and downwardly extending prongs at theend of the tube "adjacent the hook, said prongs being spacedtransversely of the instrument to permit the hook to pass between thesame, and a handle at the opposite end of said tube adjacent thefinger-grip, whereby the movement of the grip and handle towards eachother will cause the hook and prongs to approach each object betweenthem- 2. A surgical instrument comprising a rod, a downwardly extendedpointed member at one end of said rod, a lateral fingergrip at the rearend of said rod, a tube telescopic on said rod and longitudinallyslotted to guide said finger-grip and permit the ready removal of therod from the tube, a handleon the rear end of said tube adjacent saidfin tending space prongs at the outer end said tube between which prongsthe pointed member of the rod is adapted to be moved, whereby and handlewill cause the pointed member and prongs to approach each other to gripan object between them. 3. A surgical instrument comprising a rod, arearwardl y extended hook at one end of said rod, a finger grip at theopposite end of said rod, a tube telescopic on said rod and having alongitudinal slot from end to end through which said grip projects, a-

handle at the end of the tube adjacent the grip and prongs upon thesides of said slot and spaced transversely of the tube, whereby arelative movement of the hook and prongs towards each other causes theformer to engage an object in a longitudinal plane intermediate thespaced longitudinal planes of the respective pron Signed at Winne ago,in the county of Faribault and State of Minnesota, this 19th day ofNovember, 1924.
